Structural Analysis Of Delamination Of Composite Materials Using Vertical Milling Machine (GFRP)

摘要

The composite materials were available in the olden days in many forms there has been a tremendous research in the area because of its high strength to weight ratio especially in structural applications. This project deals glass fibre reinforced polymer (GFRP) composite. Fibre glass reinforced plastic are made of a plastic matrix reinforced by fine fibers of glass. GFRP is light weight, extremely strong,and robust material. Machining involves the removal of any extra or unwanted material. The maerial removal mechanism of FRP is very difficult as compared with metals due to their homogeneity and anisotropy. The delamination that occurs during milling severly influences the mechanical charecterstics of the material. In order to avoid these problems it is necessary to determine the delamination occurring due to machining operation. In order to understand the effects of process parameters on the delamination a large number of machining experiments have to be performed and analyzed using FEM model. Using FEM model the desired cutting and material parameters for minimized appearance of delamination has been developed.
